Objective. Determination of the state and features of the development of Business Intelligence as a type of decision support system in the world. Methods. The following methods and techniques of cognition were used in the research process: theoretical generalization and comparison, analysis and synthesis, induction and deduction, generalization and systematization. Results. It was established that business intelligence (BI) is a type of decision support system (DSS), which is a large-scale, interactive information system designed to ensure the collection, processing (in particular, analysis and visualization), storage and use of information for decision-making, the demand for which, in view of the significant and exponentially growing amount of information that must be taken into account by the management of the enterprise when making management decisions, the imperatives of transparency and the validity of management decisions, is constantly growing. It was determined that BI began to be actively discussed in scientific and business circles since the 80s of the 20th century. It was established that at the current stage of development, the global BI market is dynamically developing and is characterized by the following features: 1) significant and growing market capacity; 2) complex market architecture; 3) asymmetry and disproportionality of development; 4) significant structural features of the offer and a high level of market concentration; 5) significant structural features of demand. It was determined that as of 2022, the world market of BI is estimated at 29.42 billion dollars, in 2030 - 54.27 billion dollars.It is substantiated that the BI market is quite segmented, it includes the following segments: market of BI software, market of BI platforms and services; the local BI market (On-Premise BI) and the cloud BI market (Cloud BI); BFSI for Banking, Financial Services and Insurance (BFSI), IT BFS, Retail BFS, Healthcare BFS, etc.; the North American BI market, the European BI market, the Asia-Pacific region BI market, etc., the BI market of individual countries. Based on information about the state and features of the development of the segments of the BI market, it was established that the largest and most developed segments of the BI market are: the BI software market, the cloud BI market, the BI market for IT, the North American market; the fastest growing segments of the BI market are: BI platforms, applications and services market, cloud BI market, mobile BI market, Asia Pacific BI market, BI market for BFSI. It has been proven that despite the fact that the IT market is characterized by a fairly developed subject structure, the leading companies of the IT market are: IBM (USA), Oracle (USA), Microsoft (USA), AWS (USA), Salesforce (USA), Sisense (USA), MicroStrategy (USA), Teradata (USA), etc., this market is characterized by a high level of concentration, because Microsoft's share is 36% of the IT software market, 71% of cloud IT. It has been established that BI is most actively implemented by large companies.
